What are the differences between the Audi A6 and A7 models?

I am considering purchasing either an Audi A6 or A7, but I am unsure about their differences. Can someone explain to me the technical specifications and features that set these two models apart from each other?

The A6 and A7 are both luxury sedans manufactured by Audi. However, the A7 is a sportback model with a sloping rear hatch, while the A6 is a traditional four-door sedan. The A7 also has a slightly longer wheelbase and a lower roofline, giving it a more aggressive look on the road.

One of the main differences between the A6 and A7 is their engine options. The A6 offers a 2.0-liter turbocharged four-cylinder engine with 248 horsepower, while the A7 has a more powerful 3.0-liter turbocharged V6 engine with 335 horsepower.

If you value cargo space, then the A6 may be the better option for you. It has a larger trunk capacity of 13.7 cubic feet, compared to the A7's 12.4 cubic feet due to its sportier design. However, the A7's hatchback design allows for easier loading of larger items.
